REFRIGERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 256,350, dated April 11, 1882.

Application filed February 14, 1882. (No model.)

To all whom it may concern:

Be it known that I, CHARLES G. MAYER, of Nauvoo, Hancock county, Illinois, have inventeda certain new and useful Improvement in Refrigerating Apparatuses, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an apparatus for cooling rooms, and is used principally for brewery purposes, wherein a system of pipes is employed through which cold brine is cir culated to and from a cooling-tank.

My invention consists broadly in making this cooling-pipe in sections, substantially as and for the purpose hereinafter set forth.

In the drawings, Figure 1 is a horizontal section of a room beneath the floor and above the pipe system. Fig. 2 is a vertical section on line 2 2, Fig. l.

A represents the wall of the room, B the floor, and O thejoist. I) represents the feedpipe, and E the return-pipe.

The direction ofthe cooling-brine is shown by arrows.

F represents sections of pipes connected by their opposite ends to the feed and return pipes, respectively. Each section F preferably crosses the room three times, as shown, so that the brine entering one end' of a section crosses the room three times, when it enters the return-pipe and is taken back to'the coolingtank.

It will thus be seen that there will be very little friction or back-pressure of the liquid to what there would were'the cooling-pipes in one piece. Besides, it the pipes were in one piece, the brine would become heated from friction and fromtaking up heat in the pipe, and

the greater portion of its work would be without effect.

The sections are connected to the main pipes by means of short lengthsfand couplingsf'. There is a valve, f located in each length f for regulating the flow of brine, and for cutting ofl, when desired, all communication between any section and the main pipes. Should any section become stopped up so that the brine cannot circulate through it, the two valves orcocks would be closed, when the sec tion could be taken down and cleaned out; but the circulation would be going on in the other pipes or sections, and as one section is but a small proportion of the whole the temperature of the room would not be materially changed by its disconnection.

The pipes are supported by brackets G ex tending out from the walls of the room heneath the main pipes, and by rods H, hung from the ceiling, (see Fig. 2,) beneath the cooling-pipes.

As a matter of course the feed and returnpipes may run through any number of rooms .andsections of cooling-pipes be connected
